Spider wasps, i.e., the family Pompilidae, in general, and those belonging to the genus Pepsis in particular, are acknowledged to possess venoms that are algogenic to humans and thus have the parsimonious functions of causing paralysis and providing defense against predators. The morphological organization of the venom system and its complex convoluted gland closely resembles that in social members of the Vespidae. These features distinguish the venom glands of the Pompilidae from those of the sibling family Mutillidae as well as those of the family Sphecidae, which lack convoluted glands. Although the venom glands in Pepsis species are very similar in morphology to those of social vespids, the lethality of Pepsis venom to mammals is several times less than that of the social common wasps. These findings suggest that in terms of the evolution of venom activity and the associated glandular structures, there was apparently no need for social wasps to develop extra parts of the venom system for producing toxic, lethal, or powerful algogenic components. All of the glandular parts of the venom gland of social wasps were already present in pompilids (and eumenids) and, presumably, in their ancestors.

The tubular sternal glands of S. hydrophilus are tegumentary glands present only in the males and were until today unknown. They lie in the segments 6–8 and open between the 8th and 9th segment. They consist of a ramified epithelium made up of prismatic cells. The gland opening is composed of a porous plate connected to an internal cuticular complex. The porous plate itself consists of an epicuticular layer perforated by tiny pores, a mesocuticular layer with large pore canals reaching the pores, then a part with cuticular filaments. All around the porous plate, the mesocuticle makes up a cylindrical excrescence directed towards the secretory part, the free edge of which is prolonged by long mesocuticular plates called pseudomembranes; they are thin, parallel, and penetrate each of the gland cavities. Thus the tubular sternal glands appear as a ramified epidermal invagination; only the internal part of the cuticle is accompanying this invagination. The pseudomembranes might play the same role as an end apparatus for the secretory products. These glands may produce a sex pheromone which would allow the female to recognize the male.
